Nondestructive Technique in Study of Purolite NRW-5010 and Duolite A-638 Anion Exchange Resins
Abstract: The present paper is one of the interesting applications of radioactive isotopes in nondestructive technique for performance evaluation of anion exchange resins Purolite NRW-5010 and Duolite A-638. The radioactive isotopes 131I and 82Br were used to trace the kinetics of ion-isotopic exchange reactions taking place between the resin surface and external ionic solution. It was observed that for bromide ion-isotopic exchange reaction at 35.0°C, when the concentration of bromide ions …

High Strength Bolt Tightening and Verification Techniques for Steel Connections: In-Depth Study and National Survey
Abstract: The current means and methods of verifying that high strength bolts have been properly tightened is very laborious and time consuming. In some cases, the techniques require special equipment and in other cases the verification itself may be somewhat subjective. While some commercially available verification techniques do exist, there are drawbacks such as being costly, time-consuming, and impractical to use in the field. The main objectives of this project were …

Wireless Intelligent Accurate Bridge Deck Crack Inspection and Mapping
Abstract: One of the important tasks for building maintenance is building deck crack inspection. However, the inspection result in human analysis is less accurate in nature. So, a crack inspection system that uses a camera-equipped mobile robot to collect images on the building deck has been proposed. In this method, the Laplacian of Gaussian (LoG) algorithm is used to detect cracks and a global crack map is obtained through camera calibration …

Effect of TIG Welding Parameter of Welded Joint of Stainless Steel SS304 by TIG Welding
Abstract: TIG welding of stainless steel sheets depends on a large number of factors. Due to practical constraints, four dominant parameters were considered during experimental investigation. The values of the parameters were selected on the basis of material characteristics and equipment available in the industry for experimentation. The existing process of welding the hoarding pipes was studied. Design of experiments technique was used for planning the experiments. Optimum welding parameters were …
